On last night’s (July 24) Last Week Tonight with John Oliver, the show’s host took a look back at the history of the practice of using songs without permission, including Ronald Reagan’s infamous use of Bruce Springsteen’s “Born in the U.S.A.” as well as Sarah Palin using Heart’s “Barracuda,” the Democratic National Convention using Cyndi Lauper’s “True Colors,” and Donald Trump’s recent use of R.E.M.’s “It’s the End of the World As We Know It (And I Feel Fine).”

So, artists took to Last Week Tonight to record a rather hilarious song, “Don’t Use Our Song,” warning politicians in no uncertain terms, to not even try it. The all-star track featured Usher, Michael Bolton, Sheryl Crow, Ann and Nancy Wilson of Heart, John Mellencamp, Cyndi Lauper and Josh Groban.

Will the Democrats heed their warning, as the DNC is about to start? Only time will tell.
